Day by day Google service gmail account has increasing their account space and it’s approximately six giga byte (6GB) space. Can you image? How much space you need huh? It’s really amazing that, not only you can use your Google account as a storage service but also you can use for mailing service and also huge products connected with your one Gmail account.
No need to delete your old messages or sent messages or whatever you done. Even few months ago I found one Journalist who has no space on his Gmail account, because he gots huge emails a day and that should be from different services and i you also the facing the same problem you can upgrade your accounts though payments. But, I am sure I haven’t face that kinds problem 😉
As much as you can use your Gmail account and Enjoy! your free mailing life.
